usb: typec: tps6598x: Add USB role switching logic
This patch adds USB role switch support to the tps6598x.
The setup to initiate or accept a data-role switch is both assumed and
currently required to be baked-into the firmware as described in TI's
document here.

With this change its possible to use the USB role-switch API to detect and
notify role-switches to downstream consumers.
Tested with a ChipIdea controller on a Qualcomm MSM8939.
